New 1k binders for industrial furniture applications requiring high chemical resistance

 
Water-borne one-component acrylic systems have grown in popularity with furniture paint applicators in recent years because of the ease of use and the good cost positioning on the market. This has also been possible mainly due to the increase in performance of water-borne acrylic systems, in particular hardness development and improvements in early block resistance. One major area where further performance improvements are required is the chemical resistance particularly for solvents and high staining chemicals that for long could only be achieved with twocomponent or UV cross-linkable systems. This paper will illustrate how the use of new generation of 1K resins in a well designed formulation makes it possible to obtain coatings with improved chemical resistance to alcohol and coffee in pigmented systems while maintaining good hardness development as well as early block resistance, needed for industrial coating application line speeds.
